Conclusions DWI can be used to differentiate between the benign and malignant FHLs.

Authors: Kim JH, Joo I, Lee JM Abstract Hepatocellular carcinoma (HCC) can be diagnosed noninvasively with contrast-enhanced dynamic computed tomography, magnetic resonance imaging, or ultrasonography on the basis of its hallmark imaging features of arterial phase hyperenhancement and washout on portal or delayed phase images. However, approximately 40% of HCCs show atypical imaging features, posing a significant diagnostic challenge for radiologists. Another challenge for radiologists in clinical practice is the presentation of many HCC mimickers such as intrahepatic cholangiocarcinoma, combined HCC-cholangiocarci...

Rationale: Hepatic hemangioma (HH) is a common benign tumor with a high number of normal or abnormal blood vessels. Intrahepatic cholangiocarcinoma (ICC) is a relatively common malignant primary hepatic carcinoma (10%–15%) with high incidence rate and high fatality, yet low discovery rate in the early stages. Ultrasonography (US), computed tomography, and magnetic resonance imaging (MRI) are frequently used and indispensable imaging techniques for the diagnosis of hepatic lesions. It is possible to differentiate a liver lesion from HH with high accuracy owing to their different patterns and hemodynamic characterist...

CONCLUSION: There are unique geographic, political and financial limitations to healthcare delivery in the Caribbean. Nevertheless, clinical outcomes are acceptable in the established, low-volume hepatobiliary centers in the Eastern Caribbean. PMID: 30820269 [PubMed]

Rationale: Available literature states that the common reasons for non-traumatic spontaneous liver rupture are hepatocellular carcinoma, macronodular cirrhosis, hemangioma, and other tumors; gallbladder perforation is not cited as a cause. Patient concerns: The patient presented with sudden-onset right upper quadrant pain with tarry stool for 3 days after eating with dysphoria and increasing thirst; gradually, hemorrhagic shock developed. He had no history of trauma, no background of chronic hepatitis, and no cirrhosis. Diagnosis: Hemorrhage secondary to spontaneous rupture of intrahepatic cholangiocarcinoma. Inte...

We present a case of a hepatic sclerosing hemangioma in which an unusual magnetic resonance imaging (MRI) and computed tomography (CT) appearance lead to radiographic concern for gallbladder carcinoma. To the best of our knowledge, this is the first case in the literature of a hepatic sclerosing hemangioma mimicking a gallbladder carcinoma.

We report a case of atypical hepatic hemangioma mimicking HCC-CC: A 59-year-old man was referred to our hospital for a hepatic lesion that was 4.7×3.6 cm in size and located in segments 2 and 3 of the liver. Serum alpha-fetoprotein (AFP) level increased from 17.03 ng/mL to 374.9 ng/mL. The patient was positive for hepatitis B. Diagnoses: Atypical hepatic hemangioma. Interventions: US, CT, MRI and Tc-99m RBC liver scans were performed. Dynamic contrast-enhanced MRI showed no uptake in the corresponding area during the arterial phase, peripheral nodular enhancement during the portal phase and delayed phase,...

Abstract Background &AimsTo analyse elastographic characteristics of focal liver lesions (FLL)s and diagnostic performance of real‐time two‐dimensional shear‐wave elastography (RT‐2D‐SWE) in order to differentiate benign and malignant FLLs. MethodsConsecutive patients diagnosed with FLL by abdominal ultrasound (US) underwent RT‐2D‐SWE of FLL and non‐infiltrated liver by intercostal approach over the right liver lobe. The nature of FLL was determined by diagnostic work‐up, including at least one contrast‐enhanced imaging modality (MDCT/MRI), check‐up of target organs when metastatic disease was sus...
